The sacrifice of a Soldier is not measured by the medals he wears. The unfathomable courage in a split second is when the real sacrifice is made. Bravery is cultivated in the most critical hours of our lives; in a decision that is often not intentional, but innate.

For CPT (RET) Florent Groberg, his hardest battle came after the fight. August 8, 2012, changed his life forever. Eight seconds was the only separation between life and death. From this tragedy rose a man who is fiercely passionate about leadership, mental health advocacy and sharing stories about the heroes we've lost. But those eight seconds took something from him. Here is the story of CPT Groberg's unexpected bravery.

In an interview with We Are The Mighty, Groberg said, "After the ceremonies, the awards and the newly acquired celebrity, I was alone. My new life was hard. Being in the hospital was hard. The surgeries, the pain and the lack of sleep and privacy only made matters worse. For years I wasn't myself. I was angry that I was alive. I survived, and my brothers didn't. They were leaders that had families. Kennedy had a wife and one-year-old twins. I was single. I had no one, only survivor's guilt. Four of my brothers were killed that day: August 8, 2012.

"The day started off as normal, well, as normal as it can be downrange. We were headed to a meeting in the governor's province. This was a green zone, so not much ever happened there. I was working as the security detachment commander. The task was simple: Get everyone to and from the meeting safely. Easy enough, right? Our team proceeded to travel outside of the wire. We were carrying high ranking officials that day, so of course, precautionary safety measures were in place.

"As we traveled further outside of the wire, I received notification that the security detail at our arriving destination had dispersed. This left me with an eerie feeling. Two motorcycles approached our convoy on the bridge. I noticed a structure to the left … someone was standing there. As the motorcycles stopped, the drivers dismounted and began to flee. The person near the building began walking toward us.

"He had on a suicide vest.

"I ran toward him, to keep him away from the others. SGT Mahoney helped me. [The bomber] detonated his vest. The blast sent me flying. Another bomber was near and prematurely detonated his device. I was severely wounded, but alive.

"Lying in the hospital, I replayed the scenario over and over. Wondering what I could've done differently to save my brothers. I was heavily medicated and suicidal. My brain became my own worst enemy. I felt like a failure. I didn't feel worthy of being alive. I wasn't myself. My thoughts were constantly racing. I needed out.

"I learned a lot about myself during those two years. I learned that anyone is susceptible to PTS and it's okay to be vulnerable. We just don't have to hold onto those thoughts. During my hospital stay, Travis Mills visited me and reminded me of my purpose. I needed that. I had a new mission -- honoring my brothers by telling the stories of their bravery. In order to understand true patriotism, we must be willing to forgo our personal needs and put our country first. I did that. Not for a medal. I was just doing my job. I was willing to fight for what I was proud of."

On November 12, 2015, CPT Florent Groberg was awarded the Medal of Honor by President Barack Obama, in a White House ceremony. In the ceremony, President Obama said, "On his very worst day, he managed to summon his very best. That's the nature of courage -- not being unafraid, but confronting fear and danger and performing in a selfless fashion. He showed his guts, he showed his training; how he would put it all on the line for his teammates. That's an American we can all be grateful for."

Countless veterans, service members and civilians agree. Krista Simpson, who lost her husband SSGT Michael Simpson recently had the opportunity to hear CPT Groberg speak at the Military Influencer Conference. Her reaction to his speech was profound. "There is something so remarkable about a leader who has the courage and intelligence to allow his people to guide him through something that can be life or death," she said. "The humbling honor to serve his country wasn't lost on Medal of Honor recipient, CPT Florent Groberg from the moment he put on the uniform.

"I sat in the audience watching this brave man downplay the highest honor our country awards a soldier with deep admiration. He hates being called a hero. Flo believes the heroes are the families of the men and women who gave their lives in service to our nation. He acknowledged that there were families missing out on a life with their loved ones. Tears streamed down my face as he looked at me, nodding in recognition for the final sacrifice my husband, SSG Michael H. Simpson, made May 1, 2013. It's men like Flo and our great nation that ignite the pride I have for his sacrifice."

CPT Groberg was medically retired, awarded the medal of honor and wrote a book about his experience:8 Seconds to Courage: Soldier's Story from Immigrant to the Medal of Honor. He's involved with organizations like Bravo Sierra, which helps strengthen the physical and mental wellness of current service members and veterans. CPT Groberg advocates for the mental well-being of our service members. If you are struggling with something, please speak up. CPT Groberg has a few suggestions on how you can remain mentally resilient during tough times.

For Troops:

Go have a conversation with someone you trust.

Don't go through it alone. Keeping it in only leads to negative consequences.

Remember: It's okay to be hurt. Take responsibility for your healing, get help.

For Commanders:

Don't be judgemental. Listen to your troops. Understand the cause of their discord.

Continue to evaluate the mental well-being of your troops. Incorporate training that will help eliminate the stigma of mental illness. Talk about TBIs, PTS and life after war.

Remember: Not every individual suffers the same. No one solution will fix it all. Be vigilant but remain open.

And as CPT Groberg so aptly stated, "There is an opportunity to strengthen our troops. Banding together will make us healthier and a stronger fighting force. Turn the lessons from failed missions into paths that lead to success."
